I believe NASA are building a 134 meter focal length f20 right now! 8)
Wonder if my 1DX11 will work on it


Yeah, but it's a reflector so the bokeh will be horrible :(
I'd also be guessing that its minimum focus distance might not allow it to have anything on earth in focus...

I guess it can focus down to 1.5 million kilometres:

Orbit: 1.5 million km from Earth orbiting the L2 Point

True enough. Forgot it would be in orbit... :-\

This http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=1116&Camera=979&Sample=0&FLI=3&API=0&LensComp=687&CameraComp=979&SampleComp=0&FLIComp=3&APIComp=0 would seem like a more logical comparison, no?
Yes, f/2.8
To my eyes the Canon is a little sharper in the center and the Tammy is a little better in the corners. Canon set the bar high with the II lens 5+ years ago and it appears Tamron has come very close in 2017. The significant focus breathing issues at portrait distances (detailed in Dustin Abbott's review) might be a concern for portrait photographers however.

My eyes say the same as yours.
No doubt the Tamron will be a great option.

Sigma 135 f1.8 Art; Inconsistent AF

Eldar,
I have completed calibrating my Sigma 135 F1.8 Art. I used Focal target and Focal in automated mode. camera:6D.
I also took my time to verify that caibration was valid for daylight and LED lighting conditions.
calibrated at 0.9m, 1.3m, 2.5m and 12m (infinitiy). Focal reported focus consistency no less than 98.5% through the test. In order to ensure focus consistency I then ran callibration test at each given distance 4 more times and Focal suggested very similar calibration adjustment values fluctuating around the best AFMA values and within -1/+1 AFMA units around the set value.
Lens is impressively sharp with maximum sharpness achieved at around 10m to target (near infinity) and equal to 2145 Focal units. My sharpest lens is Sigma 85 F1.4 Art with 2185 Focal units achieved at approx. 4m to target.
It is a sharp lens, not as sharp as my copy of Sigma 85 F1.4 Art. They both great lenses but produce very different images of course...

85 1.8 + 200, Tamron 85 1.8 + 200 or Canon 135?

I think I'm following...

Swapping for the mythical 135 f/2 version 2.0, correct? Because you already own the current 135 right? Because Frodo is correct. I love the 135, and while I believe it's CA is much more controlled than the 85 f/1.8 (which I own as well) it is from that era of glass from Canon where it is there. I also agree that the 85 f/1.8 is hard to beat for being smaller/discreet.

I can't speak for the Tamron either, and it seems pretty universally loved (and would be on my list for an 85mm prime upgrade). However I believe it suffers from CA as well.

Scanning Negatives and Slides, scanner ore macro?

MrFotoFool said:
The reason in my opinion is that cameras are meant to photograph three dimensional objects. When you photograph a flat two dimensional picture of the real three dimensional world, it is never as good. Sadly I cannot give you the technical reasons why.

A camera with a single "eye" really can't see "3D" :D Also a lot of photo work, especially in the past, was made to reproduce flat subjects, thereby it was thoroughly tested :)

Yet, not every lens is good to reproduce flat subjects at close distances (not "flat field" designs), and a good setup and care are required to get the best results - and that's true for scanners as well.

I tried for a while to get decent result with a mid-range Epson flatbed scanner, just to give up because result weren't satisfying.

High-end scanners may use "wet mounting" to obtain better results, and let's not start to talk about the quality of drum scanners vs. CCD scanners...

Modest Growth in Camera Sales According to CIPA

Great comment, thx for this.

The numbers for Sony's announcement were not exactly what it seemed either. It's people like you that can cut through the fluff. cheers!


jebrady03 said:
Although your analysis is spot on, it is missing a few key points which seem to have been consolidated into words ("A big boost coming from mirrorless cameras") when fleshing out the numbers could be informative.

All numbers are Jan-Mar, so only 1/4 of the year.

Looking at production...
Worldwide Production of Mirrorless Cameras - Year Over Year (YOY) is up 44.1%
Worldwide Production of DSLR Cameras - YOY is down 4.7%

Looking at shipments...
Worldwide Shipment of Mirrorless Cameras - YOY is up 45%
Worldwide Shipment of DSLR Cameras - YOY is down 8.3%

Breaking down shipments by region...

Shipment of Mirrorless to Japan - YOY is up 36%
Shipment of DSLR to Japan - YOY is down 9.3%
Shipment of Mirrorless to Europe - YOY is up 44.9%
Shipment of DSLR to Europe - YOY is down 15.8%
Shipment of Mirrorless to Americas - YOY is up 78.1%
Shipment of DSLR to Americas - YOY is down 11.7%
Shipment of Mirrorless to Asia - YOY is up 39.1%
Shipment of DSLR to Asia - YOY is down .9%

Again, worldwide shipments of Mirrorless are up 45%. The ONLY region with shipment growth above the worldwide average is the Americas which has increased 78.1%. Diving into those numbers further...

Total interchangeable lens camera shipments to the Americas = 535,114
Total DSLR shipments to the Americas = 409,823 which means DSLR represent 76.6% of the market
Total mirrorless shipments to the Americas = 125,291 which means mirrorless represent 23.4% of the market.

Worldwide, as cited by CR, mirrorless accounts for 36.4% of all shipments however in the US, it's only 23.4% of the market. But again (as I've illustrated above), the MOST growth, YOY, is coming from the Americas which means that, compared with last year, the growth in the "Americas" market for mirrorless is driving mirrorless adoption worldwide - at least compared to the average adoption rate across the planet.

*note - shipments to "other areas" show a larger percent increase YOY for both DSLR and mirrorless, but the volume is so low that it only represents 2% of the entire ILC market.

Interesting numbers!

A prior manager of mine used to say (in regards to looking at performance) that looking at a single piece of data for a short period of time is like looking at a photograph - it's a moment. However, when you look at lots of sequential bits of data and they all point to the same trend, it's like watching a movie. In this case, we're looking at YOY data, which is definitely movie-like. Not only that, the data confirms what's been seen for years now. DSLR production and shipment are still declining while mirrorless is still climbing.

*disclaimer - this is just MY analysis of the numbers. It's not an indictment or condemnation of either camera line. Keep the hysterics to a minimum, please.

New Canon USA rebates, Including the EOS 5D Mark IV, EOS 77D EOS M5 and More

Might finally be time to pull the trigger on an M5. I just need to decide which bundle, if at all.

I was originally planning on M5+15-45, as it would be the smallest combo, then add the 22/2 and the 11-22. That'll be my tiny take anywhere kit. But now the 18-150 kit is only slightly more, and it's tempting me even though I know I'd probably regret it.

Review: Canon EOS 77D By TDP

Somehow the 77d feels like a replacement of the 60D, and I dont see the market for that Camera.

For someone who buys his first dslr, the only advantage to the rebel-series camera ist the LCD on top of the grip. And I assume that a lot of people dont want to pay extra money for that feature, if they are looking for an entry level camera.

More advanced Photographers will pick the 80D.
And by the way, the naming-system of Canon is a real mess. It just doesnt make sense.

Production of ef 24-105mm f/4L II: Pause, refresh, or just lagging?

monkey44 said:
Apparently, stand-alone 24-105 II is now in stock at Adorama ... not sure how many, and not sure if I missed the fact that it's now out there in other areas as well. Have been out of touch recently --

B&H is OOS tho, which is unusual that both have the same items and pricing as a general rule.

I ordered one today .., and will test it side x side with my v1 when it arrives Thursday. See how it compares in field tests. Then sell one or the other - probably keep the v2 tho, makes more sense even if for the IS ...

I've been on the fence with this based on reviews, but pulled the trigger when I saw it available alone. Was never gonna buy it as the kit anyway. Haven't planned on upgrading to the Mk IV - 5DM3 and 7D2 still give me what I need for today. We'll see in the future when the price drops on the MK IV, maybe ??

I love the focal range of this lens, it is especially useful and convenient when I go for overseas vacation. I sold my mark I and now on the fence for mark II due to the reviews. Interested to know your results. :)

Social Media tags

@cayenne - Your assumption is correct. You have to create a personal Facebook page before you can create a business one (both of which I have done). On the personal they try to get you to add all kinds of things, music preferences, fave movies, place of employment, etc, etc. However this is optional so I just left it all blank. You also have the option on your personal page of only allowing people you friended to see it (which I have done) and to not allow face recognition tagging (which I have done) and to not allow others to post on your page (which I have done). The one thing they do require when you register is to give your birth date, though you can choose to not have it displayed. I just made up a fake birthday when I registered.

Image stabilizer on or off when on a tripod?

My V1 100-400 doesn't seem to like being on a tripod with IS on. I blame the IS for ruining what otherwise would have been absolutely stunning images of the Blood Moon (I forgot to turn IS off - and yes, that is tongue in cheek - who knows how they would have turned out??? ). I haven't really noticed a difference with any of my other lenses (mostly f/4 versions of 24-105 Version 1, 24-70, 70-200, plus some others). I usually forgot to turn off IS on standard landscape shots and find it doesn't matter.

Review - Canon EF 135mm f/2L

Used to own the 135L and I can say it is a truly amazing lens. Since I have the 100L, the 135L has been underutilized as the 100L has more useability (working distance, IS, probably weight). Hence, the 135L is first to go when I need to sell for funding other stuff.

Was looking for reviews of the 135L and it brought me to this thread. Would like to know if anyone has been using the 135mm with extenders, and probably can share your experience?

Quotes from another review:

"The EF 135mm f/2L USM is Canon’s largest aperture telephoto before we enter the big white primes line. With a f/2 spec, it’s the longest you can get before the EF 200mm f/2L IS USM. Also it’s the most portable (11cm) at this length, making it ideal for journalists that can’t carry much bigger tools. Therefore the 135mm f/2 brings the best of both worlds: exotic specification and ease of use."

Canon Explains Canon Log on the EOS 5D Mark IV

Hector1970 said:
I thought CLog was a type of wooden shoe from The Netherlands. Why are Canon trying to add it to my 5DIV?
Seriously though what is CLog and how does it make a difference?.
In film making is it all about post processing as opposed to getting it right in camera?
I'm not a film maker so it's a bit alien to me but wouldn't you be better off focusing on a better film idea, script and cast rather than CLog
I probably don't appreciate the finer details in film but HD looks pretty good to me and I struggle to a huge improvement in 4K. I'm just wonder if videographers are sometimes focused on the wrong thing (the gear rather than the content) like many photographers are.

More or less, LOG is about post processing: giving you the most latitude and adjustment in the image for post. LOG images are unusable as-is. VERY flat and grey.

What were your first Canons? Analog and or digital?

My first Canon was a 35mm film EOS Elan IIe. I think the e stood for eye, as the focus was supposed to follow your eye around. I still have it and am amazed at how hefty and well-built the thing is - it's a real tank, mostly metal, too. I have no idea how many rolls of film I took with that thing, but a LOT (did my own developing, too).

Makes me feel very cool to pull it out some place like Yellowstone where everyone has big guns with long white tele's, even though I don't even put film in it any more. (No, I don't really do that, it's just hyperbole.)

You can buy them for $7 on Fleabay.

My next camera was a Pentax medium format (mucho dollars), but I sold it because I was too lazy to really use it to its potential and it was wasted on me, and I went back to the Elan, then finally to a Rebel. I've had (ruined) several Rebels (I'm hard on stuff, as I pretty much live outdoors - geologist), and I just bought an M5 and am getting ready to order a 5D Mark IV. I have one lens - a beat up 70-200L and shoot exclusively with that (rabbits and clouds and stuff), but might buy a wide angle so I can shoot shooting stars. I did once have a Pentax film camera but somebody stole it during a wild party at my house while I was gone out camping. I learned the hard way the meaning of the saying that the best camera is the one you have with you.

Canon Photo Papers

Hillsilly said:
If you are using Lightroom, you can use the soft proofing mode to make adjustments to the image and compensate for the differences.

It won't help if the ICC profile was created with different printer settings. You'd need to create a new profile for that paper with the 'hacked' settings. Still the paper type settings control, AFAIK, things as how much ink is used, and the dots characteristics. Different settings may not be good for a given paper surface.
